OEM No/Model: HYDAC Electronic Pressure Transmitter For Shipbuilding And Offshore HDA 3400,HDA 3700,HDA 4000, HDA3000, HDA7000, HDA8000
This pressure transmitter, which has been specially developed for shipbuilding and offshore applications, is based on a very
robust DMS sensor cell. All parts in contact with the fluid are in stainless steel, and are welded together. Since no seals are required
in the sensor chamber, leakage is eliminated. The 4 .. 20 mA output signal in two conductor technique enables connection to the relevant evaluation electronics. Areas of application are pressure monitoring on marine transmissions, diesel engines, pumps and general hydraulic and pneumatic systems.

This pressure transmitter has been specially developed for shipbuilding and offshore applications and is based on the HDA 4000 series. By using ceramic measurement cells, absolute and relative pressure measurements can be made in the low pressure range. Stainless steel measurement cells are used for measuring in the high pressure range.
The Digital Display Unit HDA 5500 is a microprocessor controlled display and monitoring unit designed for control panel mounting. Different versions are available with a maximum of 3 analogue inputs and 4 relay outputs. The analogue input signals are displayed according to the measuring scale selected by the user. Each of the 4 relay outputs can be allocated to each of the 1 to 3 sensor inputs or to the differential between input 1 and 2. The PT100 temperature probe can be connected directly to the unit.
The pressure transducer series HDA 4100 is equipped with a ceramic pressure measurement cell with thick-layer DMS, which was specially developed for absolute pressure measurement in the low-pressure range
The The pressure transducer series HDA 4300 is equipped with a ceramic pressure measurement cell with thick-layer DMS, which was specially developed for relative pressure measurement in the low-pressure range.<
